The KiCad project lives in the dhairyashah1/USBee32-S2 repository on GitHub; these links point at the commit this page was built from.

USBee32-S2: common questions

What microcontroller does the USBee32-S2 use?

The USBee32-S2 is built around the ESP32-S2-WROOM-ESP32-S2-WROOM, from the ESP32 family.

How big is the USBee32-S2 PCB?

The USBee32-S2 measures 28.1 × 68.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the USBee32-S2?

47 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the USBee32-S2 design files?

From the dhairyashah1/USBee32-S2 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the USBee32-S2 design in my own project?

Yes, under the terms of its MIT license, which dhairyashah1 chose for the repository.

Can I test firmware for the USBee32-S2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
